ENGINE-STARTER.

Specification of Letters Patent.

Patented July 4, 1916.

Application filed August 2, 1915. Serial No. 43,273.

and pertains especially to a, mechanical starter for internal combustion engines.

It is an object of this invention to provide a starter having a power accumulator which, when fully charged, automatically disconnectsTthe gearing'between the power accumulator and a source of ower.

It is another object of this invention to provide a starter in which the gearing connecting a power accumulator and a source of power will be thrown out of engagement, the starter thrown into engagement'with the crank shaft of the engine to be started, and abrake released, thereby supplying the power for turning over the eng ne.

A further object of my invention is to provide a winding mechanism for a mechanical starter; which is operatedby the vibrator of the vehicle body with respect to the frame.

Embodiments of my invention are illustrated in the accompanying drawing, in

which: 1

Figure 1 is an elevation partly insection of a preferred form of my starter. Fig. 2 is a side elevation of a detail. Fig. 3 isa side elevation showingthe brake mechanism. Fig; {i is a section as seen on the line 4-4 of Fig. 1. Fig. 5 is a modified form of the winding mechanism.

Referringto Figs. 1, 2, 3 and 4, a frame is indicated at 6 provided with a bearing 7 for a shaft at one end of the frame, and a bearing 8 at the opposite end. Frame 6 is provided witha track 9' extending longitudinally of the frame and adjacent the bearing 8. Rotatably mounted in the bearings 7 and 8 is a shaft 9 which is provided with a longitudinal groove 10 adaptedto receive sliding rods. Fixedly secured to the shaft 9 is a brake drum 11 suitable for a brake band 12, the latter being of the usual type. Brake band 12 is secured at one end to a bracket 13, and at the other end to a lever 1 1 of the bell crank form, and .ispivotally mounted upon the frame 6 as indicated at 15.. A vhelical spring 16 holds the brake hand against the brake drum. 1 g

'A bevel gear 17 is rotatably mounted upon the shaft 9. The hub 18 of the bevel gear is provided with a radial aperture whichis 'counterbored. as indicated at 19and receives a cap 20. Mounted within cap 20 is a detent pin 21 which is pressed downwardly by a helical spring 22, thereby providing means for clutching the bevel gear 17. to the shaft volution of the spiral spring 24 a striker 25- is mounted in a position such that it may engage a trigger. An over-hanging arm 26 is mounted upon the frame preferably int'e;

gral therewith, and pivotally mounted upon it 1s a trigger 27 so balanced that the rightfl'f hand end normally will. extend downward by its own weight, Shaft 9 hasadjacent one end thereof, .a helicabflange 28 forming a screw thread. Mounted upon-the shaft 9 is a ring member,- 29 which ,is' internally grooved or threaded and adapted-to engage with the thread 28. Instead of. the; flange" 28, shaft,.9 may be provided with ,aheiic'alf groove and ring member 29 profirided with a flange; Ring member 29 has 3. depending lug 30which is grooved along its'lower side as indicated at 31, and so di'spose'dfthat the shaft 9 is received within the groove, A J .90

helical spring'32 abuts the bearing- 8 audit shoulder on the ring member 29 tending to force the ring member into engagement with the threads 28. i A pinion 33 is slidably mounted u on a shaft 34 and so disposed that it may e en gaged with the spur gear 23; Shaftf34 is 4 shown as an extension ofthe crank shaft of the engine; A collar-.35 is rotatably mountedupon amember 36 which is secured to'th'e pinion 33. Secured to thecollar 35 isa link arm 37, thereby providing means v sliding thd'pinion 33-011 the shaft 34 into and out of mesh with the spur gear A lever-.38 is pivotally connected to link 37.

A helical spring 39 normally retracts the lever 38 and the link37, holdingpinion'33 in a position out of mesh' with spur gea'r 23. Lover 38 is so positioned that when it is I It is within the scope of my invention to wind the spring manually or by any other means. It will be Obvious that I have provided a starting mechanism suitable for automobiles, or one which may be used upon any internal combustion engine especially those of small horse power.

\Vhat I claim is:

1. A starter, comprising in combination a shaft; mechanism for operatively engaging the said shaft with the crankshaft of an internal combustion engine, but normally out of engagement therewith; a brake mechanism normally holding said shaftagainst rotation in one direction, but permitting rotation in the opposite direction; mechanism connecting a source of power to said crank shaft; a clutch normally engaging said-last named mechanism with said shaft; a power accumulator operatively secured to said shaft; means operated by said power accumulator to release saidclutch when said power accumulatoris charged; and mechanism for simultaneously releasing said clutch, said brake mechanism and operatively engaging the first named-mechanism with said shaft. v

2. A starter comprising a shaft; a gear secured thereto; means for operatively engaging the gear with the crank shaft of an internal combustionengine; a brake secured to said shaft normally holding the shaft gagement, releasing said brake, and operacrank shaft of an-internal combustion en-v tively engaging the first named gear.-
